ABSTRACT

A new and distinct cultivar of New Guinea  Impatiens  plant named ‘Fisupnic Chersweet’, and particularly characterized by the combined features of bi-colored flowers, white to pale pink color and purple-red markings; relatively large, nearly round, flat to slightly cup-shaped flowers; flowers borne on long pedicels well above the foliage; dark-green, elliptically shaped leaves; vigorous growth, and tall, only moderately tight plant habit; and early to medium flowering response.

GENUS AND SPECIES OF THE PLANT CLAIMED

[0001] New Guinea Impatiens hawkeri W. Bull (hybrid)

VARIETY DENOMINATION

[0002] Fisupnic Chersweet

BACKGROUND OF THE INVENTION

[0003] The present invention comprises a new and distinct cultivar of Impatiens, botanically known as New Guinea Impatiens hawkeri, and hereinafter referred to by the cultivar name ‘Fisupnic Chersweet’.

[0004] ‘Fisupnic Chersweet’ is a product of a planned breeding program that originated from a hybridization made by the inventor, Birgit C. Hofmann, in a controlled breeding program in Hillscheid, Germany, in 2000.

[0005] The female parent was the variety ‘Alexis’ (U.S. Plant patent application Ser. No. 09/765,324, abandoned), characterized by having bi-colored pink and red flowers, blackish-green foliage, small leaves and relatively short, compact plant habit. The male parent was a proprietary seedling, designated K00-6162-2 (unpatented), characterized by having bi-colored light pink and red colored flowers, dark green foliage, and moderately small plant habit.

[0006] ‘Fisupnic Chersweet’ was discovered and selected as a flowering plant within the progeny of the stated cross by the inventor in April 2001 in a controlled environment in Galdar, Gran Canaria, Spain.

[0007] The first act of vegetative or asexual reproduction of ‘Fisupnic Chersweet’ was accomplished when cuttings were taken from the initial selection in July, 2001, in a greenhouse in Galdar, Gran Canaria, Spain, by, or under the supervision of the inventor.

[0008] Horticultural examination of plants grown from these cuttings initiated in the spring of 2002, in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Fisupnic Chersweet’ are firmly fixed and are retained through successive generations of asexual reproduction.

[0009] ‘Fisupnic Chersweet’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length, without, however, any variation in genotype. The following observations, measurements, and comparisons describe plants grown in Hillscheid, Federal Republic of Germany, under green-house conditions which approximate those generally used in commercial practice.

BRIEF SUMMARY OF THE INVENTION

[0010] The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fisupnic Chersweet’, which in combination distinguish this impatiens as a new and distinct cultivar:

[0011] 1. Bi-colored flowers, white to pale pink ground color and purple-red markings;

[0012] 2. relatively large, nearly round, flat to slightly cup-shaped flowers;

[0013] 3. flowers borne on long pedicels well above the foliage;

[0014] 4. dark-green, elliptically shaped leaves;

[0015] 5. vigorous growth, and tall, only moderately tight plant habit; and

[0016] 6. early to medium flowering response.

[0017] Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fisupnic Chersweet’ is the patented variety ‘Fisimp 130’ (U.S. Plant Pat. No. 13,691), and the parental variety ‘Alexis’.

[0018] In comparison to ‘Fisimp 130’, ‘Fisupnic Chersweet’ has more distinct star-shaped markings on flowers, while ‘Fisimp 130’ has almost no stripes on petals, only a large splotch on the upper petals. Additionally, ‘Fisupnic Chersweet’ has a somewhat more bluish hue. While the foliage appears similar, the plant habit of ‘Fisupnic Chersweet’ is somewhat taller than that of ‘Fisimp 130’.

[0019] In comparison to ‘Alexis’, ‘Fisupnic Chersweet’ has larger leaves, lighter colored foliage, and much more vigorous growth habit.

BRIEF DESCRIPTION OF THE DRAWING

[0020] The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Fisupnic Chersweet’ with colors being as true as possible with illustrations of this type. The photographic drawing shows a side view of a typical flowering plant of ‘Fisupnic Chersweet’.

DETAILED BOTANICAL DESCRIPTION

[0021] In the following description color references are made to The Royal Horticultural Society Colour Chart (RHS). The color values were determined indoors from plants growing in a green-house in May 2003, Hillscheid, Germany.

[0022] The description is based on plants which were planted as rooted cuttings in 12 cm pots in late February 2003, and then grown in the greenhouse at 16° C. minimum temperature. Most observations and measurements were made after the beginning of flowering in mid May, when the plants were about 12 weeks old.
